IME, RTCs seem to be inconsistent in getting trained to come for handfeeding. We had many that would learn quick, and then some, like these, that appear very slow to learn:
Just saw your video Victor, i am so sorry for the loss of the RTC and the TSN. I suggest creating a separate, large quarantine tank/pond, one with sufficient dimensions. The fish you rescued in this video seemed stressed due to the reasons you mentioned, but also due to the shallow water in the tank and the treatment part was the final blow. In my opinion, you should have placed the fish in a proper quarantine pond/tank, wait for a day or two for their stress to reduce, and then begin the treatment.
All good and fair, thank you brother in fish. I am a fish junky and the QT tanks get used up for non QT purposes when empty, so I prefer to treat fish and place them straight into our main tanks. I've got a lot of experience doing it but once in a while I falter. I should have kept a closer watch and checked more often on these guys in treatment. I'd catch it in time I believe. I got badly distracted by serving paying visitors to the Aquarium.Just saw your video Victor, i am so sorry for the loss of the RTC and the TSN.

You can also use kiddie pools as quarantine ponds if buying additional tanks isn't possible or hard for you.
Just my two cents
